BRICK-KILN.

SPECIFICATION forming part of Letters Patent No. 718,022, dated January 6, 1903.

Application led March Z4, 1902. Serial No. 99,687. (No model.)

To @ZZ whom, it may concern:

Be it known that I, CHAUNCEY B. PLATT, a citizen of the United States, residing at Vanmeter, in the county of Dallas and State of Iowa, haveinvented new and useful Improvements in Brick-Kilns, of which the following is a specification.

My invention has relation to improvements ited to certain and different portions of the` material in the kiln.

With the foregoing-stated objects in view the invention consists in the improved construction of parts and their arrangement and aggroupinent in operative combined and improved results.

I`have fully and clearly illustrated the invention in the accompanying drawings, forming a part of this specification, and wherein- Figure l is a longitudinal vertical section through the kiln, showing the door construction and central iiue leading to the stack, the illustration being taken on the line l 1 of Fig. 2. with the Hoor-fines, showing the transverse channel or due, the central circular or angular passage or flue, and the arrangement of the furnaces. Fig. 3 is a horizontal section similar to that seen in Fig. 2, except that the central passage is shown circular instead of angular.

Referring to the drawings, A designates the wall of the kiln, made of suitable material and of such height and to inclose such space as may be requisite to give the required oapacity to the kiln. The kiln may be of any desired contour in cross-section. I have illustrated it as round and covered with an arched and rounded roof 1, in which are made Windows 2, utilized for the purpose of examining the ware and to permit the escape of smoke in the preliminary stages of combustion. The windows are provided with any suitable closures, as 3, which cover them when desirable.

4 designates the furnaces, of any proper Fig. 2 is a horizontal section parallel construction, built in the wall of the kiln at determined distances apart and are formed with vertical flues 5, the walls of which are sealed to or built in the masonry-of the kilnwall and reach to such heights as to throw the products of combustion over the contents of the kiln, as indicated by the arrows extending from the tops of said fines. A door 6 is provided whereby access to the interior ofthe kiln is had.

On a proper foundation constitutinga door within the base of the kiln are laid a plurality of partitions 7, parallel with each other and forming the side walls of the licor-fines and extending across the interior of the kiln and also extending over and bridging transversely-arranged draft-fines 8 Sb and an angular or circular flue 9, into which the draftiiues 8 Sbopen at their inner ends. Over the floor-fines 7 are laid bricks 10, either having interstices between them for the escape of the gases into the floor-fines or made with recesses, through which the gases pass. In the angular or circular draft-flue 9 is formed apartition 1l, which closes the ilue at that point, the purpose being to divert the draft to determined parts or portions of the contents of the kiln and to prevent it from reaching others. Within the space inclosed by the inner wall of the flue 9 is a ue 8, which may be arranged at right angles to the main draft-flue 12and communicating therewith at its side, as seen in Fig. l, or it may he arranged as seen in Fig` 3 and open atits outer end into the main draft-flue. The main draft-Hue 12, as shown, opens into the stack 13 at the outer end. In the outer end of the iiue l2 is a damper 14, by which the draft through the lue may be regulated to the extent of entirely shutting it off. On each side of the fine l2 is a draft-flue 15 16, opening from the central passage-or due 9 and opening intothe stack at their other ends, as shown in Fig. A3 of the drawings. In each of the lines l5 lb' is a damper 17 1S, which regulates the draft therethrough.

lt will be perceived from the foregoing description, taken in connection with the drawings, that When the ilues l5 and 16 are closed and the main flue l2 is open the draft in the kilnis direct to the centerportion thereof; also, that, by closing the flue l2 and leaving line IOO 15 closed and opening flue 16 then the draft is substantially shut oft from one half of the kiln, and, further, it will be perceived that if the draft is stopped in lines 16 and 12 and 15 left open the other half of the kiln Will have the benefit of the arrangement, the advantages following being the complete control of the heat-currents and the closing down of portions of the kiln when the burn is completed, leaving the remaining portions still active, thereby saving fuel and labor and obtaining a thorough and even burn in yall portions of the kiln.

In Fig. 3 of the drawings the central iiuepassage is shown circular with passages leading therein and the draft-flue section 8 in alineinent with the main draft-flue and the fioor-fiue b, covering the central portion, laid at right angles to the others. The arrangement does not dilier materially from the preferred construction illustrated in Fig. 2, and the mode of operation and result are identical.

Having described my invention, what I claim isx 1. A brick-kiln having an interior compartment,'furnaces arranged in the wall of the kiln and having lues opening` adjacent to the top of the kiln, a central ue extending around the middle portion of the base of the kiln and having a partition arranged therein, radial fines opening into the opposite sides of the central flue, a flue disposed Within the space inclosed by the inner Wall of the central iue, oor-lues parallel with each other and bridging the central and radial ues, an openwork floor on the parallel floor-fines, and a main draft-Hue opening from the iiueinclosed by the central flue.

2. Abrick-kiln having an interior compartment, furnaces arranged in the wall of the kiln and having lines opening adjacent to the top of the kiln,a central flue extending around the middle portion of the base of the kiln and having a partition acrossit, radial ues opening into the opposite sides of the central flue, a flue disposed Within the space inclosed by the inner Wall of the central line, Hoor-lines parallel with each other and bridging the central and radial lues, an open-Work oor ou the parallel oor-flues, a main draft-flue opening from the flue inclosed by the inner Wall of the central ue, draft-lines yon each side of the maindraft-flue, and opening from the central flue, and dampers in the main draft-flue and the side lues.

In testimony whereof I affix my signature in presence of two witnesses.
